Robust Wideband Beamforming Based on Response Variation Constraint
Based on the tapped delay-lines(TDL)wideband model,the response variation(RV)constraint is applied to improve the frequency response consistency of the wideband beamforming.The optimization criterion of the proposed algorithm is minimizing the designed sidelobe level utmost and the constraints of the sidelobe level,interference suppression and the response variation while making the direction response of the desired signal approaches the unity response.In addition,the proposed algorithm does not require pre-steering delay compensation,and can be solved effectively with the interiorpoint method.The simulation results show that the proposed algorithm can obtain corking constant beamwidth performance,suppress the interference,and increase the output signal-tointerference-plus-noise ratio(SINR).
